It is another object of the invention to provide a multiple receptacleplug wherein the spring engaging formations for the plugs of theappliances are of a long strip extending through the plug body andwherein the fuse element is disposed centrally of the body and connectedto one of the plug terminals and spaced from a plug terminal extendingfrom one of the strips.

Other objects of the invention are to provide a fuse plug with multiplereceptacle outlets which are of simple construction, inexpensive tomanufacture, has a minimum number of parts, compact, easy to assembleand eiiicient in operation.

For a better understanding of the invention, reference may be had to thefollowing detailed description, taken in connection with theaccompanying drawing, in which:

Fig. 1 is a perspective View of the fuse plug and receptacle embodyingthe features of the present invention.

Fig. 2 is an enlarged perspective view of the receptacle as viewed fromthe side thereof having the prongs which extend into the roomreceptacle.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.

Referring now to the figures, I represents an insulating body which isrecessed on one face, as indicated at II, to contain terminal strips I2vand I3. Each strip extends the full width of the insulating body andhas a plurality of prongs I 4 which respectively extend through slots I6in the insulating body. The prongs on the strip I3 are indicated at I4.The strip I 2 has a laterally extending portion I1 which is secured tothe body I 0 by a screw I8 and outwardly from which there extends prongI9. Screws and 2| further secure the strip I2 in place upon theinsulating body.

Also in the body I0 is a recess 22 in which may be disposed a fuse 23. Aterminal clip 24 receives one end of the fuse 23. This terminal clip 24is integral with a prong 25 aligned with the prong I9. 'Ihese prongs I9and 25 enter the wall receptacle.

has a clip 29 thereon for receiving the other end of the fuse 23.

As illustrated in Fig. 1, a plug 3I of an appliance having prongs 32 canbe inserted into the front face of the insulating body I0 so that theprong 32 thereof enters the slots I6 and engage respectively with thespring portions I4 and I4.

An insulating sheet 33 fits into the recess I I and under an inwardlyextending ange 34 extending from the side thereof, Fig. 3. The prongs I9and 25 extending through this sheet 33.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as dened by the appended claim.
